CarDriver review said this .... And I quote ... Whatever they mean by this
The Edition 507 will be unveiled at the Geneva auto show in March and hit U.S. showrooms in the summer. Pricing hasn’t been announced yet, but we expect the 507 to split current C63’s base price of $62,405 and last year’s limited-edition Black Series, whose base sticker was $108,575. Not available stateside, sadly, is the C63 AMG Edition 507 wagon, which will be sold in Germany and elsewhere.
I expect it to hit close to $100k easy with some options.
My 2011 C350 4MATIC with all options was near $70K hire in Canada ... In the US that may be around $55K I believe.
BTW ... I think my C350 has plenty of power no need for more
